| 摘 要： | 单相接地短路和两相接地短路是中性点直接接地的三相电网中最常见的故障，约占所有短路故障发生总概率的８５％。这两种故障虽然接地形式不同，但二者的物理本质、内在规律，存在着明显的相似性。本文将通过逐项对比分析，着重阐明二者的对偶性。

| Abstract: | in the neutral-point solid ground three-phase network,single-phase earth fault and two phase earth fault almost account for 85 per cent in all short-circuit fault. Although they both possess different earthed forms,they have obvious similar characteristic in physical essence and inherent law. By means of comparative analysis in order,this paper puts special emphasis on clarifying their dual characteristic. |
